Dr. Julian Quast

I am working on deformation theory of mod p Galois representations of number fields with values in a reductive group G, as well as G-pseudocharacters and determinant laws for symplectic groups. Currently I am working on the trianguline variety for reductive groups and Zariski density of crystalline points in the generic fiber of deformation rings.

My position is funded by the Deutsche Forschungsgemeinschaft (DFG) - Projektnummer 517234220
